STYROFOAM™ Brand Residing Board is an extruded polystyrene foam insulation with square edges. When installed over old siding, it provides a solid, level surface for new siding materials, plus helps enhance energy efficiency, reduce condensation and create an attractive, long-lasting home exterior.
Building Code Compliance
Meets IBC/IRC requirements for foam plastic insulation. See ESR-2142. UL Classified, see Classification Certificate D369. Calif. Std. Reg. # CA T064. HUD-UMB.
STYROFOAM™ Brand Residing Board provides energy efficiency and a solid, level surface for new siding materials.

(1) R means resistance to heat flow. The higher the R-value, the greater the insulating power. R-values are expressed in ft2 • h•°F/Btu. RSI values are expressed in m2 °C/W. R-value determined by ASTM C518.
(2) Vertical compressive strength is measured at 10% deformation or at yield, whichever occurs first.
